"PLEASE -- Do not tow our truck away," read a sign taped to the windshield of an abandoned vehicle in a no-parking zone just off 13th and Massachusetts. "It broke down just as we were heading home for Christmas. We will be back soon with time and money to take care of it. Have a happy holiday! Peace on Earth, Goodwill toward Men." When appealed to thus, the police apparently had decided on clemency, saying, "If it's not a traffic hazard we'll give them a little while to get it moved."
